Applicationv led November 13, 1,914. Serial No. 871,990.

= a specification, like reference characters on tion constitutes acontinuation` in part oifinyf the drawings indicating like parts in theseveral figures. v f H rIhis invention relates tomachines for set-- tingeyelets.` The invention is herein set` forth in its application to theclenching of eyelets between two layersof an article oif work, whichoperation in the manufacture of boots and shoes is known blind eyeletingor invisible eyeleting. This applicacopending application ySerialy No.SAABS, led August l, 1914. v

An object of the invention is to provide improved mechanism by which theinsertion of-blind or Iinvisibleeyelets may be facilitated. e A p,

In accordance with a feature of the invention, the illustratedeyeletsetting tool has a clenching shoulder formed and arranged to passthrough a lacingv hole Ain one or more layers of an article of work soas to clench an eyelet between two layers of the article. Said tool isprovided with an `abutmentbehind the eyelet-clenching or4 :upsettingshoulder. In the illustrated embodiment ofthe invention, the abutmentbehindcthe upsetting shoulder of the eyelet-clenching tool and the saidupsetting'shoulder are relatively adjustable lengthwise of the clench-iing tool. In the illustrated construction the said abutment is alsoslidabl'y moi'iute'l and spring-pressed toward the work to give it aconsiderable capacity tork seli-accoinmodation to different workthicknesses.

Also in the illust-rated embodiment ofthe invention there is acontracted or reduced portion immediately behind the upsetting shoulderof the eyeletfclenchingtocl. This construction renders the end ofatheeyelet barrel less likely to catch inthe under surface of the upperlayer during the setting operation. v

- The present invention is herein illustratedl as embodied in a machineof the typeshown,

ttor example, in United States Letters Patent No. 603,023, granted April26, 1898 on application of Seymour Field, which machine is organizedy toprovide for punching the eyelet-receiving holes by a tool separatetromthe .eyelet-settino' tool. It is to be understood, however, thattheinvention in various of its aspects is not limited to embodiment in amachine 'of this type.'

For a full understanding oi the present invention reference is to be hadto the fol` lowing' description and thel accompanying drawings, inwhich- Figure l is a view in perspective showing a setting deviceembodying the invention and a punch as they are arranged in an eye`leting machine, to 'ether with a piece of work being operate upon;

Figs. 2, ,3 and A are enlarged views illustrating the operation oiinserting and clenching an invisible eyelet; and k Fig. 5 is a verticalsectional view through the setting device.

When the setting device is used in a ma chine of the type shown in saidField Patent 603,023, the lacing holes are punched by a separate ypunchprovided for that purpose, the setting device being utilized to 'feedthe work from the punching locality to the eyelet-receivinglocality,as astep in each cycle of operations. It isV unnecessary to illustrate theconstruction of the machine itself, and for the sake of clearness it isomitted lfrom'the drawings, The machine is pro, vided with a support forthe work and with a punch which is operated preliminarily` totheinsertion of the eyelet to form the eyelet hole. As shown inFig. lthe punch K is located atthe right hand side of, the setting device A.When the punch has performed its function it is retracted so that thesetting diemay be moved to the right, inserted in the hole andthenzmoved to the left to 'feed work and register the hole with thelower die E.

The upsetting die consists in a curved up` setting shoulder 1 of suchshape as to cause the end ,of the eyelet barrel forced against it to bespread or flared outwardly, and is of such diameter that it may bepassed through one or `more layers so as to ciencb the eyelet betweentwo of the layers. The clenching position of the upsettingshoulder 1 iscleanly shown in Fig. 2. F upsetting ehbulder L the settingA vi' isprovided with a recess H or contracted portion of, substantially lessIdimm-,ter than the diameter off the upsetting shoulda, .Corisequntly,when the setting device is insert'- ed in the work, the upper layer willbe momentarily stretched by the upset droid* der 1 and will then looselysurroun the recess il. Above the recess Hure Seam :device is providedwith an elon ated stem aving' an enlarged threaded rtio'n 2 at its upperend to receive" adiive'r. The portion 2 of the setting device isscrwedinto a sleeve B which is'inadeirisnchsliape and size as zo at readily-irwsfth'e lever diother carrier of an eyeletiiig max: inein place ofthe' upsetting toer oralnarily used;

Surrounding the` lower end of the si'eeve B and disposedwith its ldwefend 'sdihev'ehat above thelipsetting shoulder 1l of thefsettiiigdevice'A is an adjustable sleeve or abutment C.' Thislmember isshaped-atits lowrf'e'd' to bear lupon the surface'dftlie upper ltyer ofIthe'vvorkl and' to flatten' th riiatelland also the clenched endotlle'e'yelt barrel; so that a very smooth ap carence is' imparted to thefinished Work. emeinbr Ci provided With a longitudinali Slot 4 in oneside,y through whit: psed a'Srw 5 threaded* into the sleeveB'; A`stiif-i cornlower end' of1 the sleeve 6' and an interior shoulder formednear the-fbott'oigi of the member C. The springd; tliereibre,` normallyholds the member@ inf its lowerniost position, this position' beingdetermined by the engagemlntof thescrvv 5 with the up-` only so arias isnecessary tti-:insure the end' of the eyelt" barrel beingclehichedbeltiiltT beneath it. l As stated in myfprevious, a plication,the miberC maybe clipedli any' desired position, andthe operation of tlispring 6 eliminated if thel requirements ofI the work'arebettersei'ved'y Bysiich ari'an'gement of the parts. In4 any. case, sincftlxemember C is used to determine' thevvorking relation ofthe shoulder landthefeyeltf-receiving layers its pcsiuchrellrtivly tothe shoulder will beadjusted according'to the thickness of the material throughl which theshoulder must pa'ss to reach the desired Working position. n

Adjustment of the position of the setting shoulder l and recess H withIespect to the acting face of the member C may be eiiected byscrewingpthe setting device A into or out of the sleeve B, the' slot 3'being readily accessible for this purpose.` Astle work varies in thethickness of its layers, and also va the in their number; ibis i thesetting device, and on account of the adjustments h .disclosed .ith Abeen found prenait. dirigir ruzies or invisible eyeltwoi: suchvarieties' as are passed through a', large factory in theregulng'ponmc-of manufacture.
